CLINICAL PHARMACOLOGY
Thyroid hormone synthesis and secretion is regulated by the
hypothalamic-pituitary-thyroid axis.
Thyrotropin-releasing hormone (TRH) released from the hypothalamus
stimulates secretion of
thyrotropin-stimulating hormone, TSH, from the anterior pituitary.
TSH, in turn, is the physiologic
stimulus for the synthesis and secretion of thyroid hormones,
L-thyroxine (T
) and L-triiodothyronine
(T
), by the thyroid gland. Circulating serum T
and T
levels exert a feedback effect on both TRH

and T
levels increase, TRH and TSH secretion decrease. When
